Underscore.js

Underscore.js is a lightweight JavaScript library that provides utility functions to simplify common programming tasks. It helps developers work more efficiently by offering ready-made methods for manipulating arrays, objects, and functions—such as iterating over data, filtering items, or combining data structures. Think of it as a toolkit that streamlines coding, making complex operations easier, faster, and more readable without adding extra weight to your project. It's especially useful when handling large or complex data sets in web development, ensuring cleaner and more maintainable code.
